I have a very specific question about Max-OT and warmup sets. I've seen it recommended to begin the routine with several warmup sets. A typical reccomendation seems to be 12 reps @ 50% of the target weight, then 10 reps @ 50% of the target weight, then 6 reps @ 65% of the target weight. Assuming that the target weight is chosen to allow 4-6 reps to failure, the warmup sets are supposed to be quite easy. Now, what happens if, for whatever reason, I find that warmup sets done to this formula are unexpectedly tiring? I understand that it is undesirable to fatigue the muscles before performing the heavy, working sets. If I find the warmup sets tiring - even though they are at the reccomended percentage of the working weight and the working weight allows for 4-6 reps - whiat approach would you consider most advisable? Should I do the warmup sets at a lower percentage of the working weight, for example?
